Put the garlic cloves into the centre of a square sheet of foil. Drizzle with 1 teaspoon of extra virgin olive oil. Pull the corners of the foil together and scrunch to make a pouch.
Place the garlic pouch and quartered peppers into an air fryer (skin side down), roast for 10 minutes at 180°C/350°F. Then cook for a further 10 minutes with the skin side up. Put aside to cool. Once cooled, remove the skins and set aside. (Note 5)
Making the Pesto
Add all the pesto ingredients into a food processor and blitz until the ingredients are mixed but still have a chunky texture. Set aside for when the pasta is cooked.
Cooking the Pasta
Bring a large saucepan of water to the boil. Add the pasta and cook according to the packet instructions. Once cooked, reserve a cup of pasta water and strain the pasta.
Making the Pesto Pasta
Put the large saucepan back onto the stove over medium-high heat and add the spare teaspoon of extra virgin olive oil. Add the diced onion, cook for 2-3 minutes or until golden and soft.
Remove the saucepan from the heat and let cool for 1 minute. Add the pasta, pesto and 1/4 cup of pasta water to the saucepan and mix well. If you find the pesto still too thick for your liking, add more pasta water (about 1 tablespoon at a time) until you reach your desired consistency.
Serve immediately with extra grated parmesan and a side salad. Enjoy!
Notes
Red Peppers - You can use jarred roasted red peppers to reduce the time, look for one that is low in sodium and sugar. If they are jarred in an oil, I recommend rinsing the peppers first to remove the excess oil, as it was add to the fat content.
Cashews - Can easily be substituted for more chickpeas, pumpkin seeds or sunflower seeds in the event of a nut allergy.
Parmesan - Substitute for vegan parmesan or 1-2 tablespoons of nutritional yeast.
Pulse Pasta - You don't need a lot of pasta for this recipe as it is deceptively filling. Some pulse pastas available at the supermarkets are also gluten free.
Oven Conversion - If using a conventional oven, roast at 200°C/390°F for 12-15 minutes on both sides, or until the skin starts to blacken and come loose.
Storage - The pesto should last for roughly 3 days in an airtight container in the fridge and up to 3 months in the freezer. You can also freeze the pesto with the pasta, just allow to cool before putting into the freezer.
Nutrition - Calculated per serve, assuming 4 serves using pulse pasta.
